System to display clip positions based on tracing vessels

Abstract

A system includes a display, and a processor. The processor may be configured to obtain a three-dimensional model of a patient including one or more blood vessels and a mass that is marked for removal, determine a position of each of one or more surgical clips within the three-dimensional model, where blood flow is restricted from a region of the three-dimensional model based on the one or more blood vessels of the three-dimensional model and the position of each of the one or more surgical clips, and present, to the display, the three-dimensional model of the patient including a visual indication of the region and the mass.

What is claimed is: 
     
         1 . A method, performed by a processing device, comprising:
 constructing a 3D anatomy model including one or more blood vessels associated with a marked mass for removal;   selecting a first position for a first surgical clip to be applied to the one or more blood vessels;   determining a region including a volume of the marked mass and surrounding healthy tissue occluded by the first surgical clip;   responsive to the volume of the marked mass being below a threshold, selecting a second position for a second surgical clip to be applied and determining a cumulative region occluded by the first surgical clip and the second surgical clip; and   displaying the 3D anatomy model including the first position for the first surgical clip and the second position for the second surgical clip.   
     
     
         2 . The method of  claim 1 , further comprising displaying a visual indication of the cumulative region and the marked mass. 
     
     
         3 . The method of  claim 1 , wherein an order of selecting the first position and selecting the second position is based on the volume of the marked mass relative to a volume of the healthy tissue that is associated with each of the first position and the second position, respectively. 
     
     
         4 . The method of  claim 1 , further comprising, in response to the volume of the marked mass that is included in the cumulative region of selected surgical clips satisfying the threshold, not selecting the second position of the second surgical clip or an additional position for an additional surgical clip. 
     
     
         5 . The method of  claim 1 , further comprising selecting an additional position for an additional surgical clip in response to the volume of the marked mass that is included in the cumulative region of selected surgical clips not satisfying the threshold and in response to one or more criteria not being satisfied. 
     
     
         6 . The method of  claim 5 , wherein the one or more criteria include a maximum number of allowed surgical clips. 
     
     
         7 . The method of  claim 5 , wherein the one or more criteria include a maximum volume of healthy tissue that is allowed in the cumulative region. 
     
     
         8 . The method of  claim 1 , wherein the threshold is obtained from a configurable setting. 
     
     
         9 . The method of  claim 1 , wherein selecting the first position and the second position includes enforcing a minimum distance between the marked mass and the first surgical clip, and between the marked mass and the second surgical clip. 
     
     
         10 . The method of  claim 1 , wherein constructing a 3D anatomy model includes obtaining one or more scans of a patient anatomy, performing segmentation on the one or more scans to define structures of the patient anatomy including the marked mass and the one or more blood vessels. 
     
     
         11 . The method of  claim 10 , wherein the one or more scans includes a plurality of computerized tomography (CT) scans of the patient anatomy. 
     
     
         12 . The method of  claim 1 , wherein displaying the 3D anatomy model includes adjusting a view of the 3D anatomy model to show the region in front of other structures in the 3D anatomy model, based on a selection of the region. 
     
     
         13 . The method of  claim 1 , wherein displaying the 3D anatomy model includes presenting the 3D anatomy on a portable device and adjusting a view of the 3D anatomy model to show the region in front of other structures in the 3D anatomy model, based on a tracked position of the portable device. 
     
     
         14 . A system comprising:
 a display, and   a processor, configured to:   obtain a three-dimensional model of a patient including one or more blood vessels and a mass that is marked for removal;   determine a position of each of one or more surgical clips within the three-dimensional model, wherein blood flow is restricted from a region of the three-dimensional model based on the one or more blood vessels of the three-dimensional model and the position of each of the one or more surgical clips; and   present, to the display, the three-dimensional model of the patient including a visual indication of the region and the mass.   
     
     
         15 . The system of  claim 14 , wherein the display and the processor are integral to a tablet computer. 
     
     
         16 . The system of  claim 14 , wherein the display includes a stereoscopic display. 
     
     
         17 . The system of  claim 14 , wherein determining the position of each of the one or more surgical clips includes obtaining user input indicating the position of each of the one or more surgical clips on a portion of the one or more blood vessels. 
     
     
         18 . The system of  claim 14 , wherein the processor is further to display a volume of the region that is associated with the mass that is marked for removal and a second volume of the region that is associated with healthy tissue. 
     
     
         19 . The system of  claim 14 , wherein determining the position of each of the one or more surgical clips includes automatically selecting the position of each of the one or more surgical clips among a plurality of potential positions associated with the one or more blood vessels, to increase a volume of the mass that is included in the region, and to reduce a volume of healthy tissue that is in the region. 
     
     
         20 . The system of  claim 14 , wherein determining the position of each of the one or more surgical clips includes automatically selecting a first position that is associated with a highest ratio of a volume of the mass that is included in the region relative to a volume of healthy tissue that is included in the region.
